Oesophageal and cardia function in patients with paraoesophageal hiatus hernia

Paraoesophageal herniation: a review

BACKGROUND

Paraoesophageal hiatus herniae repair can represent a formidable challenge. Afflicted patients tend to be elderly with multiple infirmities often with cardio-pulmonary dysfunction. They may present acutely with protracted vomiting and concurrent biochemical imbalances and it is a technically demanding procedure. There are several debated issues regarding operative technique. This paper will attempt to explain the nature of paraoesophageal hiatus herniae and reviews the recommended pre-operative investigations and operative strategies available.

METHODS

A literature search was performed from Pubmed and suitable clinical papers were selected for review. When attempting to address whether meshes should be included routinely, electronic searches were performed in PubMed, Embase and the Cochrane library. A systematic search was done with the following medical subject heading (MeSH) terms: 'paraoesophageal hernia repair' AND 'mesh'. In PubMed and Embase the search was carried out with the limits 'humans', 'English language', 'all adult: 19+ years' and 'published between 1990 and 2010'. A manual cross-reference search of the bibliographies of included papers was carried out to identify additional potentially relevant studies.

RESULTS

Firm conclusions are difficult to draw due to the diverse nature of both the disorder and the presentation however principals of management can be suggested. Similarly, there is no conclusive proof of the most effective operative technique and therefore the options are described.

CONCLUSION

Due to the relative lack of cases encountered at smaller institutions, there is a good argument for centralisation of these cases into regional centres to allow research and facilitate improvements in care.

Management of acute paraesophageal hernia

BACKGROUND

Acute paraesophageal hernia is a surgical emergency presenting with sudden chest or abdominal pain, dysphagia, vomiting, retching or significant anemia. Severe cases can present with respiratory failure or systemic sepsis. This can be due to gastric volvulus, incarceration, strangulation, severe bleeding or perforation. Traditionally this has been treated with an open surgery. The purpose of this study is to develop a management algorithm and evaluate the role of a laparoscopic approach for these cases.

METHODS

A retrospective chart review was performed for patients operated on for paraesophageal hernia at the Peter Lougheed Centre from 2004 to 2007 inclusive. Patients admitted with acute symptoms requiring emergency surgery were selected for the study.

RESULTS

Twenty patients were identified. Seventeen patients underwent successful laparoscopic repair including reduction of the hernia content, excision of the sac, crural closure, and fundoplication (Dor or Nissen). Fifteen of these were done semi-urgently. Three patients had open repair. One patient was converted to open due to ischemic gastric perforation and peritoneal contamination. Another patient had right thoracotomy followed by laparotomy for mediastinal contamination. A third patient with a body mass index (BMI) of 49 kg/m(2) was converted to open for a type VI paraesophageal hernia. Mean operating time for the laparoscopic group was 190.5 min, blood loss was minimal, and mean postoperative hospital stay was 8.2 days. There were no significant perioperative complications. All patients were tolerating regular diet on short-term follow-up.

CONCLUSION

Laparoscopic repair of acute paraesophageal hernia is safe and feasible with low morbidity and mortality. It affords all the benefits of minimally invasive surgery in a group of patients that are often elderly and suffer from multiple medical problems. Based on our experience, we advocate the laparoscopic technique to repair acute paraesophageal hernias in patients with no obvious perforation. A management algorithm is also suggested.

Symptomatic and radiological follow-up after para-esophageal hernia repair

The treatment of para-esophageal hernia by the laparoscopic approach has been described by a number of authors. The lower morbidity of the laparoscopic approach compared with the open approach holds some attraction, however, reservations regarding the durability of laparoscopic repair exist. There is a paucity of objective follow-up data in the literature with regard to repair durability and symptomatic outcome. A review was undertaken of 94 patients over a 7 year period undergoing attempted laparoscopic repairs of para-esophageal hernia. Preoperative and operative data was collected and patients underwent postoperative interview and barium meal. Laparoscopic repair was successfully completed in 86 patients. Symptomatic reherniation occurred in 12% (10/86) of patients undergoing laparoscopic repair. These patients underwent open reoperative surgery. There were no symptomatic recurrences in patients undergoing initial open repair. Symptomatic outcome was assessed by interview in 78% (73/94) of patients at a median of 27 months (3-93 months) postoperatively. Ninety-seven percent (71/73) of patients were satisfied with their ultimate symptomatic outcome however, this group included seven patients who had required reoperative surgery for symptomatic recurrence and were therefore laparoscopic failures. In order to determine the asymptomatic recurrence rate patients were requested to undergo a barium meal. A further nine small asymptomatic recurrences were diagnosed in 42 patients having had laparoscopic repair. This represents an asymptomatic radiographic recurrence rate of 21%. Laparoscopic repair in this series was associated with a 12% symptomatic recurrence rate. The majority of patients with symptomatic recurrence underwent open reoperation with good results. Strategies for reducing recurrences should be examined in prospective series.

Laparoscopic repair of chronic intrathoracic gastric volvulus

BACKGROUND

Totally intrathoracic gastric volvulus is an uncommon presentation of hiatal hernia, in which the stomach undergoes organoaxial torsion predisposing the herniated stomach to strangulation and necrosis. This may occur as a surgical emergency, but some patients present with only chronic, non-specific symptoms and can be treated electively. The aim of this study is to describe a comprehensive approach to laparoscopic repair of chronic intrathoracic gastric volvulus and to critically assess the pre-operative work-up.

METHODS

Eight patients (median age, 71 years) underwent complete laparoscopic repair of chronic intrathoracic gastric volvulus. Symptoms of epigastric pain and early satiety were universally present. Five patients had reflux symptoms. The diagnostic evaluation included a video esophagogram, upper endoscopy, 24-hour pH measurement, and esophageal manometry in all patients. Operative results and postoperative outcome were recorded and follow-up at 1 year included a barium swallow in all patients.

RESULTS

All patients had documented intrathoracic stomach. Five of 8 patients had a structurally normal lower esophageal sphincter. All 4 patients with reflux esophagitis on upper endoscopy had a positive 24-hour pH study, and 2 of these patients had a structurally defective lower esophageal sphincter on manometry. None of the patients had preoperative evidence of esophageal shortening. All procedures were completed laparoscopically. The procedure included reduction of the stomach into the abdomen, primary closure of the diaphragmatic defect, and the construction of a short, floppy Nissen fundoplication. There were no major complications. One patient required repair of a trocar site hernia 6 months postoperatively. At 1-year follow-up, there were no radiologic recurrences of the volvulus. One patient complained of temporary swallowing discomfort and another had recurrent gastroesophageal reflux disease (GERD) symptoms caused by a breakdown of the wrap. All other patients remained asymptomatic during follow-up.

CONCLUSIONS

The repair of chronic gastric volvulus can be accomplished successfully with a laparoscopic approach. A preoperative endoscopy and esophagogram are crucial to detect esophageal stricture or shortening, and manometry is needed to access esophageal motility; pH measurements do not affect operative strategy. The procedure should include a Nissen fundoplication to treat preoperative GERD, to prevent possible postoperative GERD, and to secure the stomach in the abdomen. The procedure is safe but technically challenging, requiring previous laparoscopic foregut surgical expertise.

[Videolaparoscopic treatment of paraesophageal hiatal hernia]

STUDY AIM

The aim of this prospective study was to report the results of videolaparoscopic repair in a series of ten patients with paraesophageal hernia.

PATIENTS AND METHODS

From January 1982 to September 1998, ten patients (three men and seven women, mean age: 68 years [range: 42-87]) were operated on for paraesophageal hernia. An intrathoracic gastric volvulus was present in four patients, a severe anemia in four and two were asymptomatic. All interventions were performed laparoscopically and included sac resection, crura closure and realization of a posterior gastric valve on 270 degrees.

RESULTS

There was one irruption of gastric juice in the bronchial tree at the beginning of the anesthesia which required assisted ventilation for 3 days. The mean follow-up was 17.5 months (range: 3-50). There was no postoperative diarrhea and no gas bloat syndrome. Eight patients complained of postoperative dysphagia which disappeared within 6 weeks, except in one patient with esophageal motility disorder postoperatively discovered. None of the patients had postoperative gastroesophageal reflux. A chest X-ray performed after 1 year detected no hernia recurrence in seven patients. There was no recurrent anemia after 6 months.

CONCLUSION

The videolaparoscopic repair of paraesophageal hernias is feasible without any technical difficulties even in aged patients with precarious physical conditions. The results are good with a mean follow-up of 17.5 months.

Laparoscopic treatment of large paraesophageal hernia with totally intrathoracic stomach

BACKGROUND

Once paraesophageal hernia has been diagnosed, it should be repaired immediately because of life-threatening complications such as bleeding, ischemia, and perforation when intrathoracic strangulation or volvulus occurs. We describe our surgical strategy for treating this rare type of hiatal hernia with regard to early and late postoperative complications.

STUDY DESIGN

This was a retrospective case series from a university hospital. Twelve patients (seven women and five men) with a mean age of 64 years (range, 50-76 years) and a completely intrathoracic stomach underwent laparoscopic paraesophageal hernia repair. Seven patients had a type 2 hernia, and five patients had a type 3 hernia. Additional organoaxial volvulus was present in three patients. All patients underwent reduction of the stomach and the greater omentum, excision of the hernia sac, closure of the hiatal defect, and a floppy Nissen fundoplication.

RESULTS

Because of severe adhesions, one patient needed an open stomach reduction (conversion rate, 8%). The mean operating time was 161 minutes (range, 110-200 minutes), blood loss was minimal, and the mean postoperative hospital stay was 6 days (range, 4-7 days). There were no intraoperative complications, but early postoperative complications occurred in three patients (25%; one with dysphagia, 1 reoperation due to organoaxial gastric rotation with gastroduodenal obstruction, and one with deep venous thrombosis). No deaths occurred. Followup in all patients is complete, with a mean followup time of 21 months (range, 3-40 months). The complication rate after long-term followup was 8%, and reflux esophagitis symptoms in one patient were completely relieved by medical therapy.

CONCLUSIONS

Laparoscopic paraesophageal hernia repair was feasible and safe with low morbidity and mortality rates in this elderly patient group. To achieve good long-term results, standard surgical treatment should include reduction of the stomach, complete excision of the hernia sac, closure of the hiatal defect, floppy Nissen fundoplication, and anterior gastropexy.
